RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 762,617, dated June 14,1904.-

Application filed February 25, 1904. Serial No. 195,139. (No model.)

To all whom it may concern:

Be it known that I, LEWIs J OHN DECKER, a citizen of the United States,residing at Vermilion,in the county of Erie and State of Ohio, haveinvented a new and useful Improvement in Railroad-Ties,- of Which thefollowing is a specification.

The invention relates to a railroad-tie made of metal with a wood orfibrous cushion for the rail; and the object of the improvement is tomakethe metal part of the tie out of a simple or standard shape or sheetof metal and to attach the wood or fibrous parts thereto by simple andconvenient clamps, by which all the parts of the track are held rigidlytogether. I attain this object by the construction and arrangementillustrated in the accompanying drawings, in which- Figure 1 is a planof a short piece of track laid with the tie; Fig. 2, a detachedperspective view of the metallic part of the tie made in the form of achannel; Fig. 8, a perspective view of a single tie, showing all theparts and the manner of attaching the rails; Fig. 4, a detachedperspective view of the preferred form of clamp, and Fig. 5 aperspective view of a tie made with a plate for the metallic part.

Similar numerals refer to similar parts throughout the drawings.

The metallic part of the tie is preferably made of the channel-bar 1,which can be either a rolled structural shape or a plate having itssides bent up to form "a channel, and in the bottom near the ends of thechannel are cut the longitudinal slots 2. The wood or fibrous blocks 3are neatly fitted into the channel, after which the clamps 4 are put onthe tie. The clamps 4 are made of a plate of metal bent to neatly fitaround the metallic and fibrous parts of the tie and having the sideedges bent inward and joined preferably along the middle line of thebottom of the clamp, thus forming the flanges 5, which are adapted to beentered into the slots 2 in the web of the channel-bar. The clamps areput in place by springing out the flanged edges and then telescoping theclamps over the ends of the tie toztheir proper position, when theflanges will enter the slots, and the parts of the tie are thus boundtightly together. By making the channel-slots and clamp-flanges of equallength the clamps are held against endwise movement. The transverseapertures 6 are cut in the upper side of the clamp, preferably of awidth to neatly receive the bottom of the rail. so that it rests on thefibrous block, and in the edges of the apertures are provided thenotches 7, adapted to receive the spikes 8, by which means when therails are laid and spiked on the tie all parts of the track are heldrigidly together.

The metallic'part of the tie can be madeof a flat bar, as l in Fig. 5,and the fibrous blocks fastened thereto by the clamps in-the same manneras described for the channelbar; but the channel-bar is of course thepreferred form, because of the increased vertical stiflness it gives tothe tie.

WhatI claim as my invention, and desire to secure by Letters'Patent, is-

1. A railroad-tie comprising a bar having longitudinal slots in itsunder side, fibrous blocks on the bar, and clamps around the bar andblocks having inturned flanges on adjoining edges adapted to be enteredin the slots,

there being apertures and notches in the upper side ofthe clamps adaptedto receive the rails and the spikes.

2. A railroad-tie comprising a bar having longitudinal slots in itsunder side, fibrous blocks on the bar, and clamps around the bar andblocks having inturned flanges on adjoining edges adapted to be enteredin the slots.

3. A railroad-tie comprising a channel-bar having longitudinal slots inits web, fibrous blocks in the bar, and clamps around the bar and blockshaving inturned flanges or adjoining edges adapted to be entered intheslots, there being apertures and notches in the clamps exposing theblocks and adapted to reto this specification in the presence of theceive the rails and spikes. subscribing Witnesses.
